This page is not to be confused with the official course web site. You need to pay attention to the course web page since all official information will be posted there.
At this website I will post the solutions to the weekly exercises, and you have the possibility to leave a comment or two on these solutions. You are encouraged to do so. I prefer open questions on this site, but you may also contact me on my email email@example.com or you may stop by my office in room 4466.
